ATCO American Technology (MM)

American Technology Corporation (ATC) (NASDAQ: ATCO), a leading provider of directed sound products and technologies, today announced that it will unveil and demonstrate the newest member of its LRAD� product line, the LRAD 300X(TM), at the Force Protection Equipment Demonstration (FPED VII), being held May 19 - 21, 2009 at the Stafford County Regional Airport in Stafford, Virginia.

FPED VII is conducted by the U.S. Army Product Manager, Force Protection Systems under the sponsorship of several federal agencies including the Office of the Under Secretary of Defense For Acquisition, Technology & Logistics, the Department of Homeland Security, the Joint Staff, and others. FPED brings together knowledgeable leaders from around the world and puts them in contact with manufacturers with equipment solutions for physical security/force protection needs. FPED provides leaders and decision makers from the Department of Defense, Federal departments and agencies, and selected state/local law enforcement and corrections agencies the opportunity to observe, and become familiar with, commercial, off-the-shelf (COTS) physical security/force protection equipment available for procurement and testing within 90 days of the demonstration.

ATC's LRAD 300X is a compact, lightweight solution for use on small vessels, common remote-operated weapon systems, and most military and armored vehicles. It can be easily transported to provide security personnel long-range communications and a highly effective hailing and warning capability where needed. The LRAD 300X produces focused, 100% intelligible voice transmission over 88dB of background noise beyond 200 meters. It can communicate in excess of 1500 meters depending on local terrain and environment. LRAD 300X operators have the ability to issue clear, authoritative verbal commands, followed with powerful deterrent tones to influence the behavior of targeted threats.

"We received significant input from military organizations in the design of the 300X," remarked Tom Brown, president and CEO of ATC. "Along with the LRAD 100X(TM), 500X(TM), 1000X(TM) and the remotely-operated LRAD RX(TM), we have assembled a formidable line of Long Range Acoustic Devices(TM). LRAD systems are tailored for use by law enforcement and emergency responders, land/sea-based military and commercial security personnel, homeland defense and border enforcement agencies, and for wildlife control and bird strike avoidance."
